RJ-45 connector Hirose H7642.4-10, black, pack of 10

Hirose H7642.4-10 RJ-45 connectors in black, supplied as a pack of 10, are modular 8P8C terminations designed for creating and repairing Ethernet cables and network patch leads. These connectors accept standard stranded or solid conductors used in twisted-pair network cabling and are intended for use by technicians and installers when producing custom-length cables or replacing damaged terminations.

Advantages

These RJ-45 connectors provide consistent electrical contact for all eight conductors, enabling reliable data transmission for Ethernet networks. The black housing offers a discreet finish suitable for visible installations or colour-coded cable assemblies. Supplied in a convenient pack of ten, they simplify inventory management and reduce the need for frequent reordering during small-to-medium installation and repair tasks.

Suitable for

• Termination of Cat5e and Cat6 twisted-pair cables (stranded or solid)
• Manufacturing custom patch leads and jumper cables
• On-site network repairs and field replacements
• Small-scale data cabinet or office network installations

Key specifications

• Connector type: modular 8P8C (RJ-45) compatible
• Housing colour: black
• Pack quantity: 10 connectors
• Contact design: eight-contact termination for twisted-pair conductors
• Intended cable types: compatible with typical UTP/STP twisted-pair network cables

How to use

Strip the outer jacket of the network cable to expose the twisted pairs, untwist and align conductors according to the chosen wiring standard (T568A or T568B). Trim conductor ends to the appropriate length and insert them fully into the connector until the cable jacket seats inside the housing. Use a compatible crimping or termination tool to secure the contacts and ensure reliable electrical connection. Verify continuity and pair wiring with a network cable tester before deploying the cable.

Usage recommendations

For reliable results, use a quality crimping tool matched to modular RJ-45 connectors and avoid excessive untwisting of pairs to maintain performance. Keep spare connectors on hand for field repairs and replace any connector that shows physical damage or poor contact during testing.
